水溶性肥料对花椰菜产量和效益的影响

Effects of Water-soluble Fertilizers on Cauliflower Yield and Benefit

为缓解目前蔬菜生产中水资源利用率低、肥料养分流失严重等问题,开展了2种水溶性肥对花椰菜产量及效益的影响。研究结果表明,水溶性肥能够有效促进花球膨大,其中天泽丰水溶性肥可以使花椰菜667 m2产量提高133.33 kg以上,每667 m2产值提高666.65元,而肥沃森腐殖酸水溶性肥产出投入比最高,达33.27∶1。花椰菜灌施水溶性肥,增产增效明显,可应用于今后水肥一体化技术研究中。

To relieve problems on the low utilization rate of water and fertilizer in vegetable production, we studied the effects of two water-soluble fertilizers on cauliflower yield and benefit. The results showed that, the two water--soluble fertilizers could promote the curd development of cauliflower. Applied with TZF water-soluble fertilizer, the cauliflower yield and benefit were increased by 133.33 kg/667 m2 and 666.65 Yuan/667 m% respectively. The treatment applied with FWS water-soluble fertilizer possessed highest output-input ratio of 33.27：1. Irrigating with water-soluble fertilizer, the cauliflower yield and benefit were enhanced obviously, thus, it could be used in the technology research of integrated of water and fertilizer in the future.
